- Theoretical approach to predict the Error Vector Magnitude (EVM) performance of an Orthogonal Frequency-Division Multiplexing (OFDM) system in the presence of nonlinear distortion caused by RF amplifiers is described. It is shown that the EVM model can be described by means of the autocorrelation of uncorrelated distortion noise term and a common complex gain. For the experimental validation, an EVM value of modulated signals through the fabricated HBT MMIC power amplifier is derived by the proposed method and compared with the measurement results. © 2006 IEEE.
